CMB lensing amplitude is measured 10 to 20% higher than the catalogued matter distribution predicts; the lensing signal exceeds expectations across multiple independent CMB datasets, with A_lens reaching 1.1 to 1.2 when the standard model predicts unity (Planck 2018; van Engelen 2015). The excess persists across data cuts and is one component of the broader A_lens = 1.18 anomaly (recid 16).
The standard model assumes all gravitational lensing convergence is sourced by the catalogued matter between us and the surface of last scattering, with NFW-distributed dark matter accounting for the integrated potential. Under that assumption, A_lens must equal 1 by construction. A persistent 10 to 20% excess implies either uncatalogued matter, modified gravity, or a systematic in cluster-scale baryon accounting.
SCT replaces the hot-dense-center with a superluminal collision and the thermalized debris field that became our visible universe. From this single change, the gravitational potential acquires a coherent contribution from the parent-frame mesh that ΛCDM has no concept of. Comoving baryonic structures in shared parent frames contribute coherently rather than incoherently to the gravitational potential at distant points: Φ_eff(r) = Φ_local(r) + Φ_mesh(r), where Φ_local is the locally catalogued matter and Φ_mesh is the constructive-superposition contribution from parent-frame embedding (P50, P51).
CMB photons traveling from z ≈ 1100 to us are deflected by the full effective potential. The boundary condition S(z₀) ≈ 4.4 (the present-day mesh contribution that produces the observed dark-matter-equivalent in galaxy halos) integrated over the lensing kernel gives an excess lensing amplitude of about 17 to 18% (P52, P53), in close agreement with the observed A_lens range. The same coherent-mesh contribution that flattens galaxy rotation curves without invoking a CDM particle (P54) lenses the CMB above the locally catalogued amplitude.
The same M6 mechanism resolves the cluster-substructure GGSL excess (Meneghetti et al. 2020), the cluster-mass discrepancy between weak-lensing and kinematic estimates, the S₈ tension family, and the broader A_lens = 1.18 measurement (recid 16). One coherent-mesh contribution accounts for several apparently independent observational excesses, with no fitted parameters beyond the boundary condition S(z₀) ≈ 4.4 set by halo-scale phenomenology.
Future CMB lensing measurements (CMB-S4, Simons Observatory) converging to A_lens = 1.000 ± 0.005 would refute the coherent-mesh-lensing mechanism. Independently, if the predicted relationship between halo-scale S(z₀) ≈ 4.4 and CMB-scale A_lens ≈ 1.18 fails to hold (i.e., one is confirmed without the other at greater than 3σ), the M6 framework loses its parameter-free status.
